Langsame Leistung von ArcGIS Online bei der Nutzung im Unterricht

Question

<\/HEAD>Ist noch jemandem aufgefallen, dass ArcGIS Online langsam reagiert, wenn eine ganze Klasse es benutzt? Ich habe 60-80 Bachelor-Studierende, die eine festgelegte Übung durcharbeiten, d.h. alle führen dieselben Operationen mit denselben Eingabedaten durch. Wir stellen fest, dass Pufferzonen mehr als 10 Minuten dauern, manchmal sogar viel länger, während es bei mir unter einer Minute war, als ich die Übung eingerichtet habe. Wie Sie sich vorstellen können, ist das sehr frustrierend und schreckt die Studierenden davon ab, den Dienst in Zukunft zu nutzen.<\/P> <\/P> Ist dieses Problem bekannt und, was noch wichtiger ist, gibt es etwas, das wir tun können, um die Geschwindigkeit zu erhöhen?<\/P> <\/P> Ich habe versucht, die Studierenden ihre eigenen Kopien der Eingabelayer speichern zu lassen, bevor sie Analyseprozesse ausführen, aber das scheint nicht zu helfen.<\/P><\/BODY><\/HTML>

Katy - did you ever figure this out? I'm seeing a similar thing...

Apologies for the delayed reply due to the festive break. I raised it with Esri UK support who said much the same. From subsequent classes it does seem to be a local network inadequacy, as a couple of students running their own laptops at the same time, using the wireless network, saw no slowdown. Only those using lab desktop machines on the wired network were affected.

I will pursue with our local IT, but I expect more questions from them about the typical traffic generated, which UK support have not answered. What I am not sure about is the traffic flow for running something like a buffer. I (naively) assumed it was something like: the command is sent from the local machine, the tool runs on a server somewhere using the input also held in the cloud, creates the output in the cloud and then that output is delivered back to the local user. In that situation the only network traffic is sending the command and receiving the output, which seems trivial (the layers are very simple), so I don't understand the slowdown. There must be more to it?

I'm happy to accept it's not an AGOL limitation, but it would still be useful to know if anyone else has experienced the same and seen it resolved through network infrastructure improvements.

We have not typically seen this reported and ArcGIS Online averages tens of thousands of users an hour. It could be something within your internal infrastructure? Let's investigate this further by contacting Esri technical support.
